It's nice that you're playing guardian. But if you require a huge amount of boons/abilities to remove conditions (or traits doing similar), every class which lacks either of those is at a huge disadvantage, even more so if the high-utility classes contribute an equal amount to damage (or damage itself is irrelevant, due to the lack of enrage timers or such).
I'm quite confident that once you played a thief, you'll realize just how "broken" melee in this game can be, or how much of an advantage ranged weapons are.
Now if it weren't for the fact that steal (or rather a trait for it) is one of the only abilities which applies boons to your group, and obviously it will put you in melee range - now the lack of a threat system and a medium-armor melee class usually do not end up well. It's ok for slow-swing time mobs, because you can time around that. Fast swing timer, just hope that the mob doesn't decide to turn around instantly after you stole an ability.
